Title: Structure of steel stud and partition wall
Inventor: SATO KAZUHIRO
IPC: E04C3/32
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To improve sound insulating performance and fire resistance by forming the cross section of a steel stud into such a shape that U-shaped section and inverse-U-shaped section are vertically continued and the whole is formed into the inverse-U shape or the U shape. SOLUTION: Two abutting materials 2 are connected by a bent buffer part 3 so that a steel stud 1 having S-shaped or inverse S-shaped cross section is formed. In executing it, a ceiling runner is installed on a ceiling surface, a floor runner is installed on a floor surface, and the steel studs 1 are installed at some intervals between the ceiling runner and the floor runner so that a wall substrate is formed. An underlayer wall panel is fixed to the abutting parts 2 of the steel studs 1 by screws and a facing wall panel is fixed on the underlayer wall panel by staples.  Sound transmitted to the wall panel can be thus eliminated from being connected between the wall panels in a straight line and in a short distance because of the buffer parts 3 of the studs and the transmission route of the sound becomes long so that the vibration is damped and sound insulating performance between the wall panels is improved.

Title: Atomic oscillator
Inventor: HASHI TOSHIO
IPC: H01S1/00
Filed: 1982-06-17
Abstract: PURPOSE:To increase the lifetime of a lamp and to reduce the size of the same by supplying sufficient exciting power at the time of starting firing of the lamp at the lamp fire starting time, and lowering the exciting power after firing. CONSTITUTION:The output of a photodetector 6 is amplified by a DC coupling amplifier 7 until the background reaches a practical voltage level, and the output of a DC amplifier, and further only the resonance signal is further amplified to practical level. The fire or non-fire of the lamp is discriminated by utilizing the DC component of the output of the DC amplifier 7a in the preamplifier of the resonance signal, and the power of a lamp exciter 1 is controlled. In other words, the oscillation of the exciter is strengthened to fire the lamp 2 at the starting time, and when the lamp 2 is fired so that the output of the amplifier 7a is detected, the oscillating level of the exciter is automatically lowered. In this manner, the exciter can be excited with weak power except the starting time, and a start pulse generator is made unnecessary.

Title: System for decoding error correcting code
Inventor: YAMAZAKI TOKUKAZU
IPC: H04L1/00
Filed: 1987-04-30
Abstract: PURPOSE:To improve an error correcting capacity by executing the decoding after a flash bit part included in an systematic bit string, which is the bit string of the same structure as an input information string, is forcibly 0 at a decoding side. CONSTITUTION:When a systematic convolution code is used, a systematic output is deleted and transmitted out of the coding bits generated by the flash bit and at the receiving side, all 0 bit strings are added to the part concerned again and decoded. When the flash bit of all 0 is inputted to a K bit coder, the systematic components of the coding bit generated by these are naturally all 0. Thus, by deleting, transmitting and adding the all 0 part at the receiving side, the influence of a transmission error to occur at the part can be removed.
